Bill Gates

Traditionally the worst part of the holiday gift giving season, Secret Santa generally sends offices around the world into a tizzy. Employees often try and fail to get something for their co-workers that won’t just sit in a drawer somewhere. Alas, any gift purchased from a CVS that stay under the $20 limit are not destined to be anyone’s favorite.

But every now and then you get that person who is willing to break with tradition, spend a little more, and make everyone else in the office feel bad. That person this year was Bill Gates, former richest man in the world and current one of the richest men in the world.

Gates, who has done these Reddit Secret Santaexchanges for the last few years, seemed to outdo even himself, presenting Reddit user Aerrix with a ton of video game merch, including a Nintendo NES Classic, some Zelda gloves, and an X-Box, which he presumably didn’t even pay for. He’s probably just re-gifting that one.

“Merry Christmas to all yall out there, and to Mr. Gates, who has the biggest heart and REALLY KNOWS HOW TO TREAT A GIRL TO SOME VIDEO GAMES (and video game paraphernalia)! I’m just blown away by his generosity, which went even further than all these gifts because he submitted a donation to code.org in my name to give more students the chance to learn computer science, which is AWESOME because it’s something near and dear to my heart as my husband is a programmer and my brother has a degree in computer science!

Thank you SO SO SO SO SO SO SO SO much Mr. Gates! I’ll never EVAR forget this Christmas!!!!!!!!!!!!!!!! :D :D :D”

Reddit does these Secret Santa exchanges based on interests. She smartly picked video games. Check out everything that was waiting for her under the tree:

Back in November, Bill Gates visited a plant that turns poop into water, and he took a nice big gulp.

The machine is called an Omniprocessor, and it uses a steam engine to convert raw sewage into electricity, clean drinking water and ash. On top of that, it produces enough excess energy to power itself.

"I watched the piles of feces go up the conveyer belt and drop into a large bin. They made their way through the machine, getting boiled and treated. A few minutes later I took a long taste of the end result: a glass of delicious drinking water."

The visit was part of The Gates Foundation's efforts to improve sanitation in poor countries. A few years ago, he asked people to try to reinvent the toilet as a possible solution to the problem.

The Omniprocessor was built by the Seattle-based Janicki Bioenergy, which will be conducting a pilot test of the machine in Dakar, Senegal in late 2015.

So how did the water taste?

"The water tasted as good as any I've had out of a bottle," Gates writes. "And having studied the engineering behind it, I would happily drink it every day. It's that safe."

Bill Gates, Charlie Munger and Warren Buffett participated in a "selfie" taken by CNBC's Becky Quick in Omaha. In a live interview, Buffett said based on his experiences with college students who visit Omaha, selfies are "all the rage." Estimated net worth of the three men in the picture: $143.1 billion.

What do you think happened when Bill Gates challenged the greatest chess player in the world to a match? He was embarrassingly defeated. Magnus Carlsen, 22, beat the founder of Microsoft in just over one minute of playing. Watch Carlsen's eyes as he continually stares at the chess board as though he has every move figured out almost before Gates even makes it.
